PRIMARY BATTERY.

Specification of Letters Patent.

'Application filed 'December 9, 1910. Serial No. 596,394.

To all whom-- t may concer/n.'

Be it known that I, Cuantas B. SCHOEN- Menn, citizen of the United States, and resident of lVaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Primary Batteries, of which the following' is a specification.

The present invention refers to plate 4types of this class of battery, and furthermore wherein ai" increased `positive electrode surface is rovided adjacent to the faces of the negative electrodes so as to c0- aet and insure a uniform, though increased amount of c. In, f. at a comparatively small additional cost.' This 'form of battery is particularly desirable since in many instances two of them will do the work which formerly required three of the old type of cells and again in other instances one will do the work which two of the smaller type cells were required. to do. In this connection it will also be noted that'less jar room would be required thus again making the battery particularly desirable.

The intention may obviously be carried out by the use of diiferentconstructions of holding frames and suspending means, therefore I do not wish to be contincd to the particular form of construction shown in the drawings and upon which similar characters of reference will be found to designate like or corresponding parts throughout the several figures and of which,

Figure l, shows a side edge View of my improved assembled battery elements, snspendcd within a suitable containing' jar. Fig. 2, is a central vertical cross sectional View otl the assembled batt-ery elementshown in Figs. I and 3, and taken on line 2-2 of Fig. 3, and Fig. ifi, is a side view of the said assembled clement as shown in the preceding drawings.

Referring in detail to the characters of reference marked upon the drawings 5 inl dicates a containing jar and 6- the cover therefor. The cover is rovided with two holes the central one ov which serves for the` attaclnnent of the suspending rod 7, while the outer one serves for the passage of the flexible wire S to be connected with the element. The suspending rod 7 is provided with washers 'and nuts 9 whereby it is securely fastened to the cover and is further provided with a nut 10 for the connection of a. lieldy wire 11 which through the said suspending rod is electrically connected with the negative electrodes 12 of which there are two in number. These plates are alike in construction and are formed of compressed copper. of oxid Aof suitable size, shape and proportion; These plate electrodes are each contained within metal frames that are mechanically'and electrically connected by, means of a yoke. 13, to the before mentioned suspending rod 7. The said `frames as shown include a U shaped wire portion 14 having an upwardly disposed loop 15 that is seated in a groove 16 formed in the two sides and top portion ot' the insulating blocks 17. The vertically disposed' wire sides of this vframe 'are arranged against the side edges of the negative plate while an upper and lower channel frame 1S and 19 respectively serve to engage the top and bottom edges of the said negative plate. The insulating blocks are thus seated intermediate of the loop portion of the'wire frame and the top cross piece 18 and are properly held by means of a. sheet metal clip 20 that is stamped up to shape and provided with holes on opposite sides Ito receive the upper port-ions of the wire frame 14. The lower extremities 21 of this clip is disposed against the top surface of the cross piece 1S in a manner to tend to force the same down against the top edge of the plate when the nuts Q2 on the lower end of the U shaped wire frame are turned up tight against the lower cross piece 19 thus insuring a rigid assemblement of the parts together. The intermediate upper portion of the clip is punched and otherwise pressed to form a pocket for the head of a short bolt 't2-l which is provided with suitable nuts and serves to connect the clip and the yoke together,

The insulatinf blocks for the two plates are located in the top portion of the frame and arc provided with a cross hole for the reception of a bolt 9? which passes therethrough and likewise through the upper portions of the three positive` zinc electrodes i 25 and 26. The two former of these electrodes are. arranged on the outside of the negative electrodes while theA latter and heavier one designated as26 is located be tween the negative eletrodes and the insuvbolt are electrically connected with the three positive electrodes -though insulated from the co-acting electrodes, which as beforestated have their lconnection through the. suspending rod. Thev action of the battery therefore isi directly between the adj acent faces of the'opposing electrodes to the extent thatvthe inner surfaces of the two outer positive plates co-act with the Aouter faces of the negative plates while the two outer faces of the thick inner positive late similarly cofact with the inner faces ot the two negative plates. The inner positive plate is made of substantially double the thickness of the outer positive plates, to provide an increased amount of material to suitably work out the adjacent sides of the two negative plates and thus insure all parts loit' the battery running out equally.

Having thus described my invention what I claim and desire to secure by Letters Patent isl. In a primary battery of the class described, the combination of an assemble element, comprising a pair of -vertically ar ranged compressed oXid of copper negative electrodes, an insulating block att-ached ...to-

cach of `said electrodes, a vertically disposed positive plate arranged between the 'said blocks andthe compressed oxid of copper negative electrodes, an. additional vertically disposed positive electrode arranged on the opposite andv outer side of each of the itwo said negative electrod es. means for mechanically and electrically connecting the positive electrodes, means for mechanically and electrically connecting the negative electrodes, and a single suspending means for suspending the assembled element within a battery ]ar.

2. In a primary battery of the class described, the combination of an assembled element, comprising a pair of vertically arranged compressed oxid of copper negative electrodes, an insulating block attached to each of said electrodes, a vertically disposed ositive plate `arranged between the. said locks and compressed oXid of copper negative electrodes an additional vertically disposed positive electrode arranged on the opposite and outer side of each ofv the sald negative electrodes, a bolt passing throughthe' blocks `and positive` electrodes for contrically connecting nectingv the same,'a yoke for mechanically i and electrically connecting the negative electrodes, and a single suspending rod for suspending the assembled element within a battery ar. 'n Y 3.
